mosin semi auto?
new idea to design a mosin to be semi auto by replacing bolt with a new one i will engineer and design make it so gas fires a piston built into bolt and chambers new round after first shot, this principle would work but we would be limited by the number of rounds. in practicality the system would work like so. load like normal on mosin and prepare to fire, after firing gas pushes on bolt, internal piston is pushed back and spring behind piston pushes piston into place chambering a new round and being ready to fire. a basic system for a basic rifle, im imagining this to be semi auto and having it so all mechanism is in new bolt. should i make it bent ?
